als' any awel@ ment a aber of hos@ from the inside thereof by pushing a mandrel, on `which is disposeda sticky patch, into said tube and pressing thelatter onto said mandrel, wherey by the patch is united with thetube.

tion cian apparatus of this kind byrwhich it is possible to mend .successively for instance vleaky places by means .of the mandrel inserted low the cover of the mandrel, may be brought directly underneath the place of leakage and now the patches are uncovered and, with theirk full adhesive power, connected with the wall of the tube.` f f y The apparatus according tothis invention consists of Ia cylindric mandrel closed by two covers, one of the latter being'rotatable with re'- `specty to the other cover and connected with a 2Q f the mandrel and furnished with an opening for the discharge oiA patches, while thezother cover carries anr interior tubular core with cups for the patches and means are-provided for disposing a cup exactly below the opening for the discharge of patches. f f

According to a' further construction one of the said covers is rigidlyconnected with a screwshaft which is engagedl by a sleeve, adapted to` 3omove on the tubular core inthe longitudinal `direction thereof and on its outside provided with y the cups which are disposed `in the rnannerofy the screw thread. f

.The mandriL, provided with one or more sticky patches, is pushed into` the tube to be and after its patch-discharge-opening is disposed opposite the damaged place of thetube, one end ofr the mandrel is heldvfast in thejtube .figli while the second end thereof is turned, `so that a patch passes underneath the said damaged place andk is connected withthe tubeby pressl,ing from outside the latter .on to the mandrel. The same procedure is repeated if ay number of ,455.; damaged places are lmended in'succession. i The mended place is pressed by a screwclamp This invention relates to a special construc-` in the tube,` wherebyr the patches, protectedjbe# tubular member, constitutingthe outer jacket of l mended until the damaged places are' reachedl onUline-IIIv-Qll of Fig. 1.1ll Fig. l shows theyman-f` drei or apparatus within a tube at the place to be mended. n A tubular member 1 suited to the usual diameter, of a tube is connected at one end, 60 by a set screw 2, with a head piece 3 and an. ns'erted screw shaft r4 in such manner, that when holding the tubular member l neither said shaft nor said head piece are rotated. A head piece 51s inserted rotatable 'at the other endof the 6 5r y tubular member 1 and is connected witha tubular core 7 by means of a set screw 6. Aset screwv 8 connects the core 7 with a sleeve 9, which engages the screw threads of the shaft e by means ofrv projectlonsl. The Screw 8 engages a slot 7pxl0 ofthe core 'I and therefore, when rotating the head piece 5 with respect to the head piece 3 `which is held fast, the sleeve 9 slides in the annular space formed between the outertubular member l and the core 7. sponds to a complete revolution of the head piece y 5. A long screw bolt 11 facilitates the insertion 'of thehead pieces 3 and 5 and axially but rotatably yconnects the latter. Thewouter tubu-y lar `member l is provided with an opening l2 PQl ifor the removal of patches. Whenturning the head piece 5, the cups 13 distributed on the sleeve 9 in accordance with', the screw thread of the shaft e caribe broughty successively underneath said opening 12 for the insertion or removal of 85V 'the patches.

klThenumber of cups 13 depends on the size of the ypatches and the diameter ofthe mandrel.

A circular piece of linen, placed into a cup 13 and coated with unvulcanized rubber, is soaked 90 with a rubber-solvent beforebeingcovered.y In the positions of the rotary head rpiece 5 with respect to thetubular member 1 inwhichthe patch-discharge opening 12 coincides with one ,of`

.thevcups 13, balls located. in recesses '14 yof the 95;,

rotary'head piece v5 and subjectedto the pres-` sure of springs engage bearings 15 which `are arranged in a ring 17 held `in place in the tubular member 1 by ja sleeve 16;, Therefore when turning ther head piece lonly the engagement 190 of the balls is to be watched in order to bring the patch in the next'cup 13 exactlybelow the discharge opening 12 and to cement the patch to the tube by pressing it onto the tube-wall above thedischarge opening 12. According to the illus- 3119"?,

tratedembodiment five damaged places 'can be. mended' in succession, because the mandrel or apparatus for the common, fire-extinguishing lhoses permits the arrangement of six cups.A 13. f

If lthe apparatus is used .for the application of 11 f The stroke correwith an opening in its Wall, a head piece fixed to one end of the latter, a lsecond head piece rotatably attached to thev 'other' end `of said member, acore located in said tubular member and xed to the rotatable head piece, and cups on saidcore for the disposition of repair-patches.

2. Apparatus for securing repair-patches tobe cemented to the inner wall of a tube or hose, comprising in combination a tubular member with an opening in its Wall, a head piece xed to one end of the latter, a second head piece rotatably attached to the other end of said member, ra core located in said tubular member and fixed to the rotatable head piece, cups on said core for the disposition of repair-patches, and meansin said member and the rotatable head piece securing the latter in the adjusted position.

' 3. Apparatus for securing repair-patches to be cemented to the inner wall of a tube or hose, comprising in combination a tubular member with an opening in its wall, a head piece rotatably attached to one end of said member, a tubular core located in the latter, a second head piece fixed to the other end of said member, a screw shaft arranged Within Asaid core and fixed to said second head piece, means on said core to engage the thread of the screw shaft, and cups arranged'on said core in a screw-line.
